While I do agree that there's definitely room for improvement, I found the game pretty fun, rather addicting, especially considering how it appears you whipped this game up pretty quick! And hey, it starred Jon and Jacque, and they're just the coolest.
It was awesome playing as Jacque having to protect Jon from the camels, and he shot lasers, which was eching cool! The Jontron theme was certainly motivating and also so badass!
I can definitely see this being expanded on in the future, and there's so much you could do with it, if you decide to make it into a full blown game with powerups, upgrades, new moves, and a story.
Anyway, pretty good game, fun all around and Jontron's theme always makes me smile!
